Abstract
The utility model relates to a high temp. endoscope pickup protector, which is used in an endoscope industrial television supervision system of a high temp. furnace. The protector adopts a cylindrical enclosed structure with three layers to achieve cooling effect. The utility model adopts endoscope type, and the angle of the front end of the utility model is altered according to the position of a supervised product, so the reflection of state of the supervised product in the furnace is more visual in exact. The utility model has the advantages of small size, compact structure, reasonable assembly of an opticator and a camera, and convenient installation, debugging and maintenance on site. The utility model can work continuously for a long time under the condition that the pressure of shield gas is low (200-1000 mm H<2>O) and the water flow is small. The protector can be widely used in the high temp. furnaces of building material, metallurgy, electric power, chemical industry, etc.
Description
The present invention is used for the protective device of high temperature kiln spy industrial tv monitoring system.In the prior art; the protective device of high temperature kiln industrial tv monitoring system (shown in Figure 1); it has the enclosed construction (1) of a double-deck garden cartridge type; gamma camera is installed in the interior cover glass (8) by the opticator front of garden tube and externally videotapes; by cooling water the temperature in the tube of garden is remained in the 0-40 ℃ of scope in the interlayer of double-deck garden tube, gases at high pressure penetrate through tracheae (5) some apertures (4) on the end curved surface before install.But existing protective device volume is big, and the cooling water flow is big, and protective gas pressure height needs special-purpose air machinery.In addition, existing protective device can only be used for monitoring by observation panel outside the kiln.
The purpose of this invention is to provide in a kind of high temperature kiln that is used for various atmosphere except that highly basic, strong acid the protective device that videotapes that monitors production status in the kiln with the spy steady and continuous.
Formation of the present invention is to peep in the high temperature to videotape three layers of garden cartridge type enclosed construction of protective device employing, and its air chamber (1) is a taper.Gas with certain pressure flows into air chamber (1) by inlet suction port (10) through tracheae (6), forms malleation in air chamber (1).Air chamber (1) is made the structure (Fig. 3) that 4-90 ° of five equilibrium four-footed supports, and on the cannelure of embedding protective glass headstock (14) (Fig. 4), is fixed on the protective device with screwed gland (2).Peeping the elbow that videotapes the protective device front end in the high temperature can make arbitrarily angled according to the position that is monitored object in the kiln.Opticator (4) and gamma camera (9) keep coaxial in protective device, only need to reach the purpose that shows best images by the angle of distance between adjustment gamma camera (9) and the opticator (4) and gamma camera (9).
This protective device monitors by spy and change protective device angle can intuitively and truly reflect the state that is monitored object in the kiln; it is little to have volume; compact conformation; installation, debugging and maintenance are all more convenient, have the used low (200～1000mmH of protection bleed pressure again
2O), the less (1m of the flow-rate ratio of water
3/ H) characteristics.This source of the gas and discharge all solve easily in general factory.This protective device can be widely used in the high temperature kilns such as building materials, metallurgy, electric power, chemical industry.
This protective device embodiment is as shown in Figure 2:
This protective device is three layers of concentric garden cartridge type enclosed construction that process with common seamless steel pipe.Opticator (4) and gamma camera (9) are installed in the protective device, are equipped with quartz glass in the opticator front and are processed into the uniform cover glass of thickness (3).Through inner aqueous layer passage (5), outer water layer passage (7) flows out from water out adapter (8) cooling water then from water supply connector (13).Protective gas enters the space of protective glass headstock (14) front end by gas joint (10) through many tracheaes, forms malleation.Air chamber (1) is made the structure that 4-90 ° of five equilibrium four-footed supports; then four-footed is embedded on the cannelure of protective glass headstock (14); be fixed on the protective device with the gland that is threaded (2); make protective gas enter air chamber (1) smoothly and spray protective device then, stop kiln internal contamination thing to touch on the cover glass.The size in this protective device inwall aperture will be according to the external diameter size design of opticator and gamma camera.Each weld will guarantee higher sealing in the mill.
This protective device is installed and is adopted specific purpose tool.Have on the rear end screw thread that the female erecting tools of long handle front end is spun on opticator (4) with one, then opticator is advanced from the device rear end.With the instrument of a shape as spill; little garden cylindricality is made at its tip; be inserted in two apertures on the protective glass headstock front end cannelure; the protective glass headstock is put on the screw thread that is screwed into the opticator front end and screws from the front end of protective device; extract the erecting tools of belt length handle then out, the cannelure of the four-footed of air chamber (1) being aimed at protective glass headstock front end is tightened with gland (2).At last gamma camera is advanced protective sleeve.Angle by distance between adjustment gamma camera (9) and the opticator (4) and gamma camera (9) reaches the purpose that shows best images.Then bonnet (12) is fixedly tightened screw (11).
Fig. 1 is that the high temperature of prior art of the present invention videotapes the protective device cutaway view.
Fig. 2 peeps in the high temperature of the present invention to videotape the protective device cutaway view.
Fig. 3 peeps in the high temperature of the present invention to videotape among protective device Fig. 21 cutaway view and vertical view.
Fig. 4 peeps in the high temperature of the present invention to videotape among protective device Fig. 2 14 cutaway view and vertical view.
Claims (4)
1, be used for the protective device of high temperature kiln spy industrial tv monitoring system, the invention is characterized in, peep videotaping three layers of garden cartridge type enclosed construction of protective device employing in the high temperature, its air chamber [1] is a taper, has (200～1000mmH
